[mkgmap-dev] Strange long distance routes on Nüvi

From Andrzej Popowski popej at poczta.onet.pl on Thu Jul 27 12:08:53 BST 2017


I think TMC is supported only by NT maps. There should be TMC ID 
somewhere in img and there is additional file with extension *.trf in 
mapset, similarly like global index. It would need a lot of revers 
engineering to find how it all works. And there is not much TMC data in 
OSM. Probably only in Germany.

I have done some work in my own styles to improve long distance routing. 
This include recognizing international roads and increase of road class 
for junctions. I will try to prepare a patch for default style.

Best regards,
